bpo-34989: python-gdb.py: fix current_line_num() (GH-9889)
python-gdb.py now handles errors on computing the line number
of a Python frame.

Changes:

* PyFrameObjectPtr.current_line_num() now catchs any Exception on
  calling addr2line(), instead of failing with a surprising "<class
  'TypeError'> 'FakeRepr' object is not subscriptable" error.
* All callers of current_line_num() now handle current_line_num()
  returning None.
* PyFrameObjectPtr.current_line() now also catchs IndexError on
  getting a line from the Python source file.

debug symbols for example.

Łukasz Langa 5fe59f8e3a bpo-30983: [gdb] Fix py-bt, etc. for non-debug shared builds (#3153)
PEP 523 introduced _PyEval_EvalFrameDefault which inlines PyEval_EvalFrameEx on
non-debug shared builds.  This breaks the ability to use py-bt, py-up, and
a few other Python-specific gdb integrations.

This patch fixes the problem by only looking for _PyEval_EvalFrameDefault
frames.

test_gdb passes on both a debug and a non-debug build.

Original patch by Bruno "Polaco" Penteado.

Victor Stinner 7cc33998b8 bpo-30983: Revert changes which broke most buildbots (#3100)
* Revert "Add Bruno Penteado to ACKS (#3091)"

This reverts commit f978405b3f.

* Revert "bpo-30983: eval frame rename in pep 0523 broke gdb's python extension (#2803)"

This reverts commit 2e0f4db114.

Bruno "Polaco" Penteado 2e0f4db114 bpo-30983: eval frame rename in pep 0523 broke gdb's python extension (#2803)
pep 0523 renames PyEval_EvalFrameEx to _PyEval_EvalFrameDefault while the gdb python extension only looks for PyEval_EvalFrameEx to understand if it is dealing with a frame.

Final effect is that attaching gdb to a python3.6 process doesnt resolve python objects. Eg. py-list and py-bt dont work properly.

This patch fixes that. Tested locally on python3.6

* Replaced dict(<generator expression>) with dict comprehension
* Replaced set(<list literal>) with set literal
* Replaced builtin func(<list comprehension>) with func(<generator
  expression>) when supported (e.g. any(), all(), tuple(), min(), &
  max())

  _PyCFunction_FastCallDict() is already detected

Victor Stinner 7fc252adfb Optimize _PyCFunction_FastCallKeywords()
Issue #29259: Write fast path in _PyCFunction_FastCallKeywords() for
METH_FASTCALL, avoid the creation of a temporary dictionary for keyword
arguments.

Cleanup also _PyCFunction_FastCallDict():

* Don't dereference func before checking that it's not NULL
* Move code to raise the "no keyword argument" exception into a new
  no_keyword_error label.

Update python-gdb.py for the change.

Frame.is_other_python_frame() now also handles _PyCFunction_FastCallDict()

Thanks to the new code to handle fast calls, python-gdb.py is now also able to
detect the <built-in id method of module ...> frame.

David Malcolm 8d37ffa563 Issue #12605: Show information on more C frames within gdb backtraces
The gdb hooks for debugging CPython (within Tools/gdb) have
been enhanced to show information on more C frames relevant to CPython within
the "py-bt" and "py-bt-full" commands:
  * C frames that are waiting on the GIL
  * C frames that are garbage-collecting
  * C frames that are due to the invocation of a PyCFunction
